The lecture series “Evaluation and Evidence Based Policy Making in Germany“ is organized by the Coordination Unit “Sustainable Development in International Cooperation“ of the University of Bonn and the German Institute for Development Evaluation (Deutsches Evaluierungsinstitut der Entwicklungszusammenarbeit; DEval). In the lecture series, evaluation experts analyze and discuss the methods and role of evaluation in the context of German public policy. While the topics discussed are wide-ranging, the common thread that runs through the series is how complex issues of public policy can be assessed in a methodologically rigorous manner whilst assuring successful stakeholder management and yielding useful and timely results.
